Use bouncycastle provider for AWSConnection if available

[GoogleCodeExporter]

Sometimes on OS X 10.6.x with JDK6 loading the Hmac provider produces an 
exception that looks like the one pasted at the end of this issue. Googling 
around it seems like this is an OS X JDK bug. The patch provided allows you to 
load and use the Bouncycastle security provider if it is available on the 
classpath for encoding the AWSConnection data packet.
